Plant fossils discovered 1.5 kilometers under Greenland ice, which is at risk of melting – EXPLICA.CO – ALL NEWS IN WORL


Plant fossils, frozen under a kilometer and a half of ice in Greenland, represent a worrying indicator that this ice sheet has completely melted in previous warm periods. This is shown by the new study, published in the journal ‘Proceedings of the National Academy of Sciences’, provides solid evidence that
Greenland is more sensitive to climate change than previously believed, and runs the risk of melting irreversibly.
In 1966, US Army scientists drilled nearly a mile of ice in northwestern Greenland and pulled out a fourteen-foot-long tube of earth from the bottom. Then this frozen sediment
It was lost in a freezer for decades and was accidentally rediscovered in 2017. ....

Greenland Ice Sheet is More Sensitive to Climate Change than Previously Understood


Greenland Ice Sheet is More Sensitive to Climate Change than Previously Understood
Written by AZoCleantechMar 16 2021
In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. It was accidentally rediscovered in 2017.
In 2019, University of Vermont scientist Andrew Christ looked at it through his microscope and couldn t believe what he was seeing: twigs and leaves instead of just sand and rock. That suggested that the ice was gone in the recent geologic past and that a vegetated landscape, perhaps a boreal forest, stood where a mile-deep ice sheet as big as Alaska stands today. ....
